Diversity and Phylogeography of Southern Ocean Sea Stars (Asteroidea)
Diversity and phylogeography of Southern Ocean sea stars (Asteroidea) Thesis submitted by Camille MOREAU in fulfilment of the requirements of the PhD Degree in science (ULB - “Docteur en Science”) and in life science (UBFC – “Docteur en Science de la vie”) Academic year 2018-2019 Supervisors: Professor Bruno Danis (Université Libre de Bruxelles) Laboratoire de Biologie Marine And Dr. Thomas Saucède (Université Bourgogne Franche-Comté) Biogéosciences 1 Diversity and phylogeography of Southern Ocean sea stars (Asteroidea) Camille MOREAU Thesis committee: Mr. Mardulyn Patrick Professeur, ULB Président Mr. Van De Putte Anton Professeur Associé, IRSNB Rapporteur Mr. Poulin Elie Professeur, Université du Chili Rapporteur Mr. Rigaud Thierry Directeur de Recherche, UBFC Examinateur Mr. Saucède Thomas Maître de Conférences, UBFC Directeur de thèse Mr. Danis Bruno Professeur, ULB Co-directeur de thèse 2 Avant-propos Ce doctorat s’inscrit dans le cadre d’une cotutelle entre les universités de Dijon et Bruxelles et m’aura ainsi permis d’élargir mon réseau au sein de la communauté scientifique tout en étendant mes horizons scientifiques. C’est tout d’abord grâce au programme vERSO (Ecosystem Responses to global change : a multiscale approach in the Southern Ocean) que ce travail a été possible, mais aussi grâce aux collaborations construites avant et pendant ce travail. Cette thèse a aussi été l’occasion de continuer à aller travailler sur le terrain des hautes latitudes à plusieurs reprises pour collecter les échantillons et rencontrer de nouveaux collègues. Par le biais de ces trois missions de recherches et des nombreuses conférences auxquelles j’ai activement participé à travers le monde, j’ai beaucoup appris, tant scientifiquement qu’humainement. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

LaPira, 4, Florence, IT Kolumbo is the largest of tWenty submarine volcanic cones tectonically aligned in the transtentional Anydros basin, NE of Santorini, representing one of the most seismically active Zones in the South Aegean Volcanic Arc. Kolumbo explosively erupted in 1650 CE, causing the death of 70 people on Santorini. Explorative cruises employing ROVs shoWed the presence of a high temperature (220°C) hydrothermal field With CO2-rich discharges and accumulation of acidic Water at the bottom of the crater (505m bsl) [1], increasing the haZard of this active system. A possible magma chamber Was recognized beloW the crater at depth 9-6 km by seismic data [2], Which is separated from the storage system of Santorini, as suggested also for the mantle source by geochemical data [3]. We present neW petrographic, geochemical and isotopic data (on Whole-rock, minerals and glasses) of samples collected during the cruises. Most samples represent the juvenile products of the 1650 CE activity, characterizing the different magmas interacting before the eruption. They consist of White rhyolitic pumices With grey and black bands, also including centimetric to millimetric, basaltic-andesitic enclaves. -

In this issue of Geology, Carey et al. (2013, p. 1035) describe 300,000 tons believed to have been released in the Lake Nyos event. Of a new, interesting, and quite powerful natural example of the intersection course, we could be at an early stage of the CO2 buildup, and over time, of these concerns in describing the build-up of a large body of acidic, far larger quantities could accumulate. Carey et al. show that the local dense CO2 rich sea water in the shallow crater of the Kolumbo volcano source is an extensive hydrothermal vent fi eld, releasing almost pure close to the Mediterranean island of Santorini. -

Research Vessel POLARSTERN PS119: 13.04
Research vessel POLARSTERN PS119: 13.04. – 31.05.2019 Punta Arenas ‐ Port Stanley Sixth weekly report: 13. – 19. May, 2019 To the smoking volcano of Saunders Island Like last week, we spent the sixth week in the southernmost area of the South Sandwich Plate, from the back‐arc spreading ridge of the segments 8 and 9 in the west to the Kemp Caldera. The volcano of Kemp Caldera is part of the collision zone with the South American plate to the East. A look to our expedition logo shows symbolically the spreading ridge on the left and flowing to the right the volcanoes, fore‐arc area and subduction zone. The weather conditions, which denied from Sunday to Tuesday morning further dives, permitted not until Tuesday to dive down with ROV QUEST to the seafloor. We used the dive‐free time for the deployment of other sampling gear. On Sunday, 12th of May, we sampled the deepest area of the Kemp caldera with a 3 m long gravity corer and the multi‐corer. The until then surveyed Parasound profiles over the caldera showed in the deepest area narrow sediment layers, whose mineral and chemical composition in references to hydrothermal deposits are of huge interest. With our corers we were able to sample sediment layers of 230 cm depth, which surprised us by their colouring and diverse sediment compositions.
